TECHNICAL FIELD

The present invention relates to a quinoline compound having a melanin-concentrating hormone (hereinafter sometimes to be abbreviated as MCH) antagonistic action and useful as an agent for preventing or treating obesity and the like.

BACKGROUND ART

Feeding behavior is an indispensable action for many organisms including human. An abnormality in feeding behavior causes deviation from normal life support activities, which in most cases results in diseases. Along with the recent changes in feeding environments, obesity is becoming a social problem. It is widely known that obesity is not only a serious risk factor of life-style related diseases, such as diabetes, hypertension, arteriosclerosis and the like, but also causes arthritis and pain resulting from an excessive burden on joints of knee etc. due to increased body weight. In addition, the dieting boom and the like have increased the potential population that desires weight loss. There are many reports on eating disorders, such as hyperphagia and the like, due to neuropathy and the like, which are genetic or caused by stress.

Consequently, the development and investigation of agents for preventing or treating obesity or feeding deterrents started some time ago, and mazindol has been on the market as a centrally acting anorectic agent.

Along therewith, a number of appetite-regulating factors represented by leptin have been found in recent years, and new anti-obesity agents and anorectic agents that suppress the activity of such appetite-regulating factors have been developed. Among others, melanin-concentrating hormone is a hormone derived from hypothalamus and known to have an appetite stimulating action. Furthermore, MCH knockout mouse has been reported to show significantly decreased food intake and be lean, as compared to normal mouse, though normal in daily behavior [Nature, vol. 396, p. 670, 1998]. From the foregoing, an MCH antagonist, once completed, is expected to be a superior anorectic agent or anti-obesity agent.

On the other hand, the following compounds are known as fused heterocyclic compounds.

-   1) WO95/32967 describes a compound of the formula:

-    wherein A is CONR, in which R is hydrogen or C₁₋₆ alkyl; Q is an     optionally substituted 5- to 7-membered heterocycle containing 1 to     3 hetero atoms selected from oxygen, nitrogen and sulfur; R¹ is     hydrogen, halogen, etc.; R² and R³ are independently hydrogen,     halogen, etc.; R₄ and R₅ are independently hydrogen or C₁₋₆ alkyl;     R⁶ is halogen, hydroxy, etc.; R⁷ and R⁸ are independently hydrogen,     C₁₋₆ alkyls, etc.; m is 0 to 4; n is 0, 1 or 2; or its salt, which     has 5HT1D antagonist activity and is expected to ameliorate     anorexia. -   2) JP-A-2001/139555 describes a compound of the formula:

-    wherein R^(b) is hydrogen or C₁–C₈ alkyl and R¹ and R² are     hydrogen, C₁–C₈ alkyl and the like, that inhibits secretion of     apoprotein B and is useful for treating atherosclerosis and the     like.

Preferable examples of the salts with acidic amino acids include salts with aspartic acid, glutamic acid, and the like.

Of these, pharmaceutically acceptable salts are preferable.

Preferable examples when compound (I) has an acidic functional group include inorganic salts such as alkali metal salts (e.g., sodium salt, potassium salt, etc.), alkaline earth metal salts (e.g., calcium salt, magnesium salt, barium salt, etc.) and the like, ammonium salts, etc.; and when compound (I) has a basic functional group, inorganic salts such as hydrochloride, sulfate, phosphate and hydrobromide; or organic salts such as acetate, maleate, fumarate, succinate, methanesulfonate, p-toluenesulfonate, citrate and tartrate.

The compound (I) may be an anhydrate or a hydrate. When it is a hydrate, it may contain 0.5 to 3 water molecules.

Furthermore, compound (I) may be labeled with an isotope (e.g., ³H, ¹⁴C, ³⁵S, etc.).

Where compound (I) includes optical isomers, stereo isomers, regio isomers and rotational isomers, these are within the scope of compound (I), and can be isolated as their single compound through synthesis or separation known per se. For example, where optical isomers of compound (I) exist, those resolved from their mixtures through optical resolution are within the scope of compound (I).

Said optical isomers can be produced by methods known per se. Concretely, optically active synthetic intermediates may be used, or mixtures of racemate of the final product are subjected to ordinary optical resolution to give the corresponding optical isomers.

As the optical resolution method, methods known per se such as fractional recrystallization method, chiral column method, diastereomer method which are described in detail below and the like are employed.

1) Fractional Recrystallization Method

The method which comprises allowing a racemate to react with an optically active compound (e.g., (+)-mandelic acid, (−)-mandelic acid, (+)-tartaric acid, (−)-tartaric acid, (+)-1-phenethylamine, (−)-1-phenethylamine, cinchonine, (−)-cinchonidine, brucine, etc.) to give a salt, which is then isolated through fractional recrystallization method, followed by, when desired, subjecting the isolated compound to neutralization to obtain free optical isomers.

2) Chiral Column Method

The method of separating a racemate or a salt thereof, which comprises utilizing a column for fractionating optical isomers (chiral column). In the case of liquid chromatography, for example, a mixture of optical isomers is applied to a chiral column, such as ENANTIO-OVM (manufactured by Tosoh Corp.), CHIRAL SERIES (manufactured by Daicel Co.), and the like, which is then eluted with water, various buffers (e.g., phosphate buffer) and organic solvents (e.g., ethanol, methanol, isopropanol, acetonitrile, trifluoroacetic acid, diethylamine, etc.), singly or as a suitable mixture of them, to isolate the individual optical isomers. In the case of gas chromatography, for example, a chiral column such as CP-Chirasil-DeX CB (manufactured by GL Science Co.), and the like is used for isolation.

3) Diastereomer Method

A racemic mixture is chemically reacted with an optically-active reagent to give a mixture of diastereomer, which is subjected to ordinary separation means (e.g., fractional recrystallization, chromatography, etc.) to give single compounds. The thus-isolated single compounds are then chemically processed, for example, through hydrolysis to thereby remove the optically-active reagent site from the compounds to obtain optical isomers. For example, where compound (I) has a hydroxy group or a primary or secondary amino group in the molecule, it is condensed with an optically-active organic acid (e.g., MTPA [α-methoxy-α-(trifluoromethyl)phenyl-acetic acid], (−)-menthoxyacetic acid, etc.) or the like to give the corresponding ester-type or amide-type diastereomer. On the other hand, where compound (I) has a carboxylic acid group, it is condensed with an optically active amine or alcohol reagent to give the corresponding amide-type or ester-type diastereomer, respectively.

Reference Example 1-1 Amplification of Rat SLC-1 Receptor cDNA by PCR Method Using cDNA Derived from Rat Brain

Using poly (A)⁺ RNA derived from rat brain (Clontech) as a template and a random primer, reverse-transcription reaction was carried out. For the reverse-transcription reaction, a reagent of TaKaRa RNA PCR ver. 2 kit was used. Using this reverse-transcription product as a template and synthetic DNA primers of SEQ Nos:1 and 2, amplification was performed by the PCR method. The synthetic DNA primers were constructed such that the gene in the region to be translated into the receptor protein could be amplified, during which restriction enzyme recognizing sequences of restriction enzyme Sal I and restriction enzyme Spe I were added to the 5′ side and 3′ side, respectively, so that a base sequence recognized by the restriction enzyme Sal I would be added to the 5′ side of the gene and a base sequence recognized by the restriction enzyme Spe I would be added to the 3′ side of the gene. The composition of the reaction mixture was cDNA template 5 μl, each synthetic DNA primer 0.4 μM, 0.25 mM dNTPs, pfu (Stratagene) DNA polymerase 0.5 μl and buffer annexed to the enzyme, with the total reaction volume of 50 μl. For amplification cycle, Thermal Cycler (Perkins Elmer) was used. After heating at 94° C. for 60 seconds, a cycle of heating at 94° C. for 60 seconds, at 60° C. for 30 seconds, and at 72° C. for 150 seconds was repeated 35 times, and the mixture was finally reacted at 72° C. for 10 minutes. The amplified product was confirmed by ethidium bromide staining after 0.8% agarose gel electrophoresis.

Reference Example 1-2 Subcloning of PCR Product to Plasmid Vector and Confirmation of Amplified cDNA Sequence by Decoding Base Sequence of Insert cDNA

The reaction product after PCR conducted in Reference Example 1-1 was separated using 0.8% low melting point agarose gel and the band was excised with a razor, and subjected to minimization, phenol extraction, phenol-chloroform extraction and ethanol precipitation to recover DNA. According to the direction of PCR-Script™ Amp SK(+) cloning kit (Stratagene), the recovered DNA was subcloned to plasmid vector pCR-Script Amp SK(+). This was introduced into Escherichia coli XL-1 Blue (Stratagene) to allow transformation, after which clones containing cDNA insert fragment were selected in an LB agar medium containing ampicillin and X-gal, separated using a sterile toothpick for white clones to give transformant E. coli XL-1 Blue/rat SLC-1. The respective clones were cultured overnight in an LB medium containing ampicillin, and using QIA prep8 mini prep (QIAGEN), plasmid DNAs were prepared. A part of the prepared DNAs was cleaved with restriction enzymes Sal I and Spe I to confirm the size of the inserted receptor cDNA fragment. The reaction for determination of the base sequence was carried out using DyeDeoxy Terminator Cycle Sequence Kit (Perkins Elmer), and decoded using a fluorescence automatic DNA sequencer. The sequences of the obtained three clones were analyzed and confirmed to be identical with the gene sequence consisting of a cDNA sequence (Lakaye, B. et al. Biochim. Biophys. Acta, Vol. 1401, pp. 216–220 (1998), accession No. AF08650) encoding rat SLC-1 protein (SEQ No:3) whose full length sequence had been reported, a Sal I recognizing sequence added on the 5′ side and a Spe I recognizing sequence added on the 3′ side (SEQ No:4).

From a clone of E. coli transformed with a plasmid incorporating a gene encoding a full length amino acid sequence of rat brain derived SLC-1 and having a Sal I recognizing sequence added on the 5′ side and a Spe I recognizing sequence added on the 3′ side, whose sequence was confirmed in Reference Example 1-2, a plasmid was prepared using Plasmid Midi Kit (QIAGEN) and cleaved with restriction enzymes Sal I and Spe I to excise an insert. The insert DNA was recovered by excising, after electrophoresis, from agarose gel with a razor and applying minimization, phenol extraction, phenol-chloroform extraction and ethanol precipitation. This insert DNA was added to animal cell expression vector plasmid pAKKO-111H (vector plasmid identical with pAKKO1.11H described in Hinuma, S. et al. Biochim. Biophys. Acta, Vol. 1219, pp. 251–259 (1994)) cleaved with Sal I and Spe I and ligated using T4 ligase (Takara Shuzo Co.) to construct protein expression plasmid pAKKO-SLC-1.

E. coli DH5 (TOYOBO) transformed with pAKKO-SLC-1 was cultured and plasmid DNA of pAKKO-SLC-1 was prepared using Plasmid Midi Kit (QIAGEN). This was introduced into CHO dhfr⁻ cell using CellPhect Transfection Kit (Amersham Pharmacia Biotech) and in accordance with the attached protocol. DNA (10 μg) was prepared into a coprecipitation suspension with calcium phosphate and added into a 10 cm dish inoculated with 5×10⁵ or 1×10⁶ CHO dhfr⁻ cells 24 hours before. The cells were cultured in an MEM α medium containing 10% fetal bovine serum for one day, passaged and cultured in a nucleic acid-free MEM α medium (selection medium) containing 10% dialyzed fetal bovine serum. 56 clones of transformed cell colonies, which were SLC-1 expression CHO cells grown in the selection medium, were selected.

Reference Example 1-6 Determination of Base Sequence of Plasmid Containing Isolated Human SLC-1 cDNA

The plasmid obtained in Reference Example 1-5 was introduced into ELECTROMAX™ DH10B™ Cells by electroporation method to allow transformation, after which clones containing cDNA insert fragment were selected in an LB agar medium containing ampicillin and X-gal and separated using a sterile toothpick for white clones to give transformant E. coli DH10B/hSLC-1. The respective clones were cultured overnight in an LB medium containing ampicillin, and using QIA prep8 mini prep (QIAGEN), the plasmid DNA was purified. The reaction for determination of the base sequence was carried out using DyeDeoxy Terminator Cycle Sequence Kit (Perkins Elmer), and decoded using a fluorescence automatic DNA sequencer. As a result, the sequence depicted in SEQ No:8 was obtained.

By performing a forced swim test using SD (Sprague Dawley) rats (seven-week-old, male, body weight 233.3–266.9 g, purchased from Japan Clea), the antidepressive action of the compound of the present invention was evaluated.

First, a suspension of the compound of Example 19 in 0.5% methyl cellulose was orally administered to SD rats (n=10) (compound dose: 3 mg/kg body weight). Thirty minutes later, the rats were placed in a pipe (diameter 21 cm, height 50 cm) made of Plexiglass (trade name, made by Rohm & Haas, U.S.A.) containing tap water (water temperature 25±2° C., 30 cm deep). Immobility time of the rats for five minutes thereafter was measured using a digital video camera.

In addition, 0.5% methyl cellulose suspension without the compound was orally administered to SD rats (n=10), and the rats were subjected the forced swim test in the same manner as above and taken as a control group.

As a result, the immobility time (seconds, mean±standard deviation) of the rats of the compound administration group and control group was 15.93±5.62 and 30.86±8.71, respectively, and the immobility time was shortened in the compound administration group. In other words, it was clarified that the compound of the present invention has a superior antidepressive action.
